[development doc updates]

[Fred Drake]

The development version of the documentation has been updated:

    http://python.sourceforge.net/devel-docs/

Update for development version of Python (2.2).

This update substantially re-works the prototype support for
productions of a formal grammar.  They look better, support forward
references to symbol definitions, and allow download of an all-text
version of the complete grammar (with productions ordered the same way
as they are in the documentation sources).

"Documeting Python" now includes documentation for the LaTeX markup
used to describe productions:
